MACHINE. FOR APPLYING ADHESIVE MATERIAL TO STRIPS OF PAPER.

SPECIFICATION forming part of Letters Patent No. 439,332, dated October 28, 1890.

Application filed February 26, 1886. Serial No. 193,326- (No model.) i

To all whom it may concern.-

Be it known that I, CHARLES E. TAYLOR, a citizen of the United States of America, residing at Holyoke, in the county of Hampden and State of Massachusetts, have invented new and useful Improvements in Machines for Applying Adhesive Material to Strips of Paper and Similar Material, of which the following is a specification.

My invention has relation to improvements in machines for applying adhesive matter to strips of paper, cloth, and other material, and is especially applicable for use in the manufacture of paper boxes for preparing strips of paper of various lengths and widths to be applied to the boxes.

The objects of my invention. are, first, to provide a machine whichwill deliver a strip of material with one side having the adhesive matter spread thereon and the other side left clean and free from viscidity, and, second, to

' provide a machine which will apply paste or glue to and deliver such strips of different lengths and widths with the same certainty and expedition that a single continuous strip may be pasted and glued:

With these objects in view my invention consists in the novel construction of parts and their combination, as will hereinafter be fully specified, and especially as the same is particularly pointed out in the claims.

I have fully and clearly illustrated my improvements in the accompanying drawings, which show one practical form of machine embodying the same.

In said drawings, Figure l is a side elevation of my improved machine. Fig. 2 is a plan view of the same. Fig. 3 is a longitudinal vertical sectional view taken on the line at x of Fig. 2. Fig. 4: is a side view of the delivery-belt or carrier-stand, showing the water-tank with a roller journaled therein and the scraper for cleaning the carrying-belt. Fig. 5 is a side elevation of the glue-pan with the raising and lowering mechanism detached from the machine. Fig. 6 is a view of the feed-roll. Fig. 7 is a side view of the lower portion of the feed-table, showing the sides curved under the shaft of the feed-roller and the adjustable guide. Fig. 8 is a sectional view of the feeding mechanism, taken on an enlarged scale from that of the other figures.

In the drawings, a designates the glue-roll, preferably of iron, mounted on journals Ct in bearings in a suitable frame I), and arranged with its lower portions in the adhesive material in the glue-tank c, substantially as shown in Fig. 3 of the drawings.

d designates the feed-table, which is located at the upwardly-moving side of the feed-roller and is supported upon the machineframe in an inclined position, preferably with its end nearest the feed-roller lower than its opposite or'outer end. The feed-table is made adjustable in relation to the feed-roll to different inclines by means of depending arms (1 which are slotted, as shown, andjare. held rection for being fed straight to the feeding mechanism.

Means are herein shown for delivering the sheets from the feed-table to the glue-roll, as follows: A feed-roll f is mounted on suitable hearings in the frame, and is arranged with its circumferential face adjacent to but free from the glue-roll. It is essential that the glue-roller be placed free from contact with the feed-roll in order that the viscous material adhering to the glue-roll shall not touch the surface of the feed-roll, since in the character of the work to which the machine is especially applicable it is a requisite of good work that one side of the strip shall be perfectly clean and untouched by the paste or other adhesive substance thereon. In the present instance I have shown the feed-roll as being in part covered with emery, as seen at f in Fig. 6, to increase the frictional contact with the strips. Said feed-roll is located adjacent to the inner or lower end of the feedtable, and in the outer ends of said feed-roll are formed annular grooves f f which are engaged with bearings d d, formed by means of curved arms or prongs which project from the end of the feed-table at either side thereof, as clearly shown in the drawings, Fig. 7. Springs 8, having their rear ends secured to the sides of the frame, as at 3, project forward from their rear ends above the table and over the feed-roll and carry on their free ends a presser-bar h and feed-finger 2'. Said presser-bar and feed-finger are sustained by a support g, consisting of a cross-piece having its ends secured to the springs s and a standard proj ecting upwardly from the middle of the cross-piece, substantially as seen in the drawings. The presser-bar h is attached to a rod h, arranged to slide through guide-arms 77. upon the support g, a spring 25 being applied between one of said guidearms and a nut 15' on the rod to throw the presser downward against the strips of paper. The force with which the presser acts is regulated by turning the nut 75 on the rod 71,. The support 9 is adj ustably attached to the springs s s, so that it may be moved back and forth in its relation to the feed-roll by means of fastening-screws inserted through slots in the support, as shown in Fig. 2, the object of this construction being to vary the position of the forward ends of the layers of strips in relation to the feed-roll to suit different kinds of paper. The feed and stop finger 2' is detachably secured to the support 9 by any suitable means and serves the double purpose of holding the strip being fed against the feed-roller, so that the latter will engage and carry forward the same, and as a stop for the layers of strips above the one being fed. After the strip is engaged by this feed-finger said strip will be carried forward over the feed-roll without disturbing the other strips not being fed. To give this feed-finger and stop an elastic pressure on the strip beneath it,a rubber cushion to may be inserted between the finger and the support g, which sustains it.

The support g, with the mechanism carried by it, may be adjusted vertically by means of adjusting-screws z, passing through the end of the springs s with their threaded ends engaging the sides of the frames, as indicated in Fig. 3 of the drawings. The feeding of the strips is accomplished by the presser and feed-finger, the former resting upon and pressing the pile of strips against the feed-roll, so that the latter will engage frictionally with and carry forward the lowermost strip of the pile, while the feed-finger holds the upper strips from moving while resting upon and holding against the roller the strip which is being fed. The strips will therefore be fed forward by the feed-roll from the bottom of the pile one by one and continuously as long as the presser is allowed to act upon the pile, the feeding being stopped by drawing upwardly or backwardly the presser against the action of the spring t, which holds said presser against the pile during the feeding of the strips.

Arranged across the machine between the feed-roller and the glue-roll is a guide-piece u, and above it is another guide-piece u, approximately parallel with it, as shown. I have shown the guide it as being secured to the end of the springs s, but it may with equal practicability be secured to the side piece of the frame, the purpose of the device being to provide means for guiding and directing the strips from the feeding devices to the glueroll, the guide a at the upwardly-moving side of the glue-roll being so close to the latter as to insure the contact of the strip therewith. The guide it thus performs the important function of laying the strip on the glue-roll or causing its-adhesion thereto and then acting as a bearer or stretcher to keep the strip in contact with the glue-roll.

A glue-tank c is arranged in the frame under the glueroll and in such position that the lower part of the glue-roll dips into the contents of the tank. (Shown in Fig. 3 of the drawings.) The glue-tank c is mounted on a frame supported on pivoted supports 6, raised and lowered by a lever 7, which is an extension of one of the supports, as shown, and on the frame a is a depending standard 9, having a plate 8 on its lower end, on which a lamp or other convenient burner may be placed to heat the glue in the tank.

The glue-roll is liable to carry adhering matter in greater quantity than is required, and I therefore provide means for wiping off the surplus glue, consisting of a wiping-roll 2, mounted in bearings in a sliding box 10,

secured to the side pieces of the machine and made adjustable by the adj usting-screw 3, having its neck held in a bearing 11 on the machine-frame and its screw-threaded end engaging in a screw-threaded hole in the sliding box.

To prevent the glue from being carried over the ends of the glue-roller, I provide scrapers 4, supported on bolts 12, inserted through the frame, with theedges of the scrapers bearing against the face of the ends and extending the strips are liable to escape from the guides 16 a without being carried against the glueroll, so that in some cases they may fail to becomeproperly glued; butthe fingers pp insure the contact of all parts of the strips with the roll. The bearing ends of these fingers are beveled to a narrow edge to present narrow surfaces in contact with the roll or strip, and thus overcome the tendency to accumulate paste when from any cause they travel on the glued surface of the glue-roll.

Take-off fingers jj are mounted on a barj', arranged across the front of the machine in front of the glue-roll. Said fingers preferably extend into and rest in annular grooves 9?, formed in the face of the glue-roll, and serve to lift or separate the strips from the glue-roll and direct them from the roll to a carryingbelt hereinafter described.

On the frame adjacent to the glue-roll is journaled a roll Z, and in a suitable support, as m, is journaled a roll m, and about these is arranged a carrying-belt 70, which receives and conveys the strips from the fingers and glue-roll. This carrying-belt may be of any desired length to meet the capacity of the machine and the number of hands employed to take the strips from it and apply them to the boxes. The belt is arranged with its upper part or fold in an approximately horizontal position.

On the frame 'm' is fixed a water-tank m in which is journaled a roller m partly immersed in water in the tank and arranged to travel with its face against the belt, and on the end of the tank is fixed a scraper 5, which bears against the belt and takes off any water or other extraneous substance adhering to it, so as to always present a clean surface to the strips as they are delivered upon the belt at its opposite end.

To keep the upper line of the belt from sagging, I mount a roll m on an extension of the frame and arrange it with its upper surface to bear upon the belt, as shown in Figs. 1 and 3.

O designates aframc mounted in the frame of the machine and journaled at one end in the supports e, so that it may be lifted up from its horizontal position. In this frame are journaled two rollers n 77. and about these rollers are arranged a belt n, which is made tight by an adjustable tightener-roll m as shown. The belt at may be formed with horizontal ridges 1 arranged in alignment with points between the take-off fingers, the purpose being to provide means for preserving perfect cleanliness in the strips. As the glue-roll travels past the points of the takeoff fingers there may be a small quantity of the viscous substance carried to and deposited upon the top of the projecting point of the take-off finger, and as the end of the strip strikes the end of the take-0E finger some of this drop may be left on the extreme edge of the glazed or finished side of the paper, and if carried by pressure between the belts this small particle of paste might blur the strip on its un glued side.

from coming into contact with each other and also help to direct, the strip straight These ridges keep the belts its forward movement until entirely free from the glue-roll.

The roll 71 serves the double purpose of a carrier for the belt n and as a guide and presser to the strip as it leaves the take-off fingers and glue-roll. The strip is released upon coming into contact with the take-off fingers and its end directed forward under the roll n and upon the carrying-belt. In this movement of the strip and during its progress the roll of bears on the strip and serves to draw or hold it in close contact with the glue-roll in its entire length and width.

Motion is communicated to the roller n by the roller Z, which has a gear 19 on its shaft to mesh with the gear 20 on the shaft of roller n, and by this gearing the belt on the rollers n n is moved.

Motion is communicated to the glue-roll through a belt-pulley 13, (shown as a stepped or cone pulley,) and having a gear-wheel 14 on its shaft, which meshes, respectively, with a gear-wheel 15 on the shaft of the roller of the carrying-belt and with the gear-wheel 16 on the glue-roll, this last-mentioned gearwheel meshing with a gear 17, mounted on a stud upon the frame, and said gear-wheel 17 is attached to a second larger gear-wheel 17 which in turn meshes with a gear-wheel 18 on the feed-roll. This gearing is intended to be proportioned to'give the glue-roll a faster circumferential movement than the feed-roll. This-arrangement of the driving-gear causes the glue-roll to pull on the strip as it passes from the guide u, and thus brings the strip into close contact with the glue-roll and also spreads the glue on the strip. 7

The more rapid circumferential movement of the glue-roll may in some instances cause the paper to slip backward to some extent upon the surface of the glue-roll, thus greatly aiding the smooth and even application of the adhesive substance to the paper, it being obvious that the proper application of the adhesive substance will be facilitated by draw ing the paper over the roll. faster movement of the glue-roll will also tend to take out of the paper any slack which may be caused by the Wetting of the same, and will thus keep the paper smooth and in close contact with the surface of the roll while passing over the latter. By making the carrying belt, which takes the paper from the glue-roll,

to travel faster than said glue-roll several advantages are gained. One is that the paper is held or drawn taut over the glue-roll and all of the kinks or wrinkles which may be Such 'slightlyformed by expansion of the paper when wet by the glue or from other cause are taken out of the paper, and the same is caused to rest smoothly against the glue-roll and drawn from the same in a flat or unwrinkled condition. Another advantage gained by making the carrying belt travel faster than the glueroll is that by this construct-ion the rear end or edge of each piece or strip is more cer tainly covered with adhesive material by the drawing of the strip over the surface of the glue-roll as it is leaving the same. It is obvious that the rear end or edge of each strip or sheet may in some instances fail to receive its full supply of adhesive substance from the fact that it escapes from the guiding or feed devices before being brought into close contact with the roll. As the stripor sheet passes from the glue-roll, however, if the rear end of the sheet is drawn forward over the surface of the glue-roll, the glue will be spread or wiped upon its surface in an obvious manner.

The operation of the machine is as follows: The layer of strips of paper is laid on the feed-table between the guides and the ends of the pile allowed to rest upon the feed-roll under the presser-bar and against the feed and stop finger, so that the surface of the feedroll will engage the under side of the lowest strip of paper and draw it forward. As the strip is fed forward its advance end is directed between the guides, which are located between the feed-roll and the glue-roll, and said guides direct the strip upon or against the surface of the glue-roll. ried onthe surface of the glue-roll until it reaches the take-off fingers, and after the ad- Vance edge of the strip comes in contact with and adheres to the glue roll it is drawn tightly withsome force against the glue-roll, owing to the fact that the glue-roll moves faster than the feed-roll. WVhen the end of the strip reaches the take-0E fingers, it is raised from the surface of the roll and directed under the roll 71 and upon the carrying-belt, by which it is delivered to the workmen. As the strip is carried from the glue-roll to the carrying-belt the strip will be drawn tightly by reason of the more rapid movement of the carrying-belt, thereby taking all kinks or wrinkles from the strip and at the same time insuring the application of the adhesive material to the rear end of the strip, which will be drawn or wiped over the surface of the glue-roll in passing from the latter. If it is desired to stop the feed, all that is necessary to do is to lift the presser-bar of the feed and the strips will notbe fed, or if a strip is being fed the feed will not proceed after that strip is delivered if the presser-bar be lifted. The feed may be accomplished by hand, when desired, by lifting the feed device free of the feed-roll and directing the strips to the glue-roll through the guide. Feeding by hand is sometimes desirable when oddsized strips are used.

The device herein shown for feeding paper strips or sheets one by one from the feedtable to the gluing devices, and consisting generally of a feed-roll and opposing presser and feed-finger, does not constitute an essential part of my invention, inasmuch as any other well-known or preferred form of feeding device may be employed for delivering the sheets to the gluing devices; or the ma- The strip is car chine may be without any special devices for feeding the sheets separately, and ordinary feed-rollers or other similar and common form of device for carrying the sheets toward the.

glue-roll may be substituted for the particular feeding devices shown, the sheets in such case being delivered to the machine one by one by hand. The employment of a stationary guidesuch as the guide-bar herein shownbetween the feeding device and the glue-roll, operating to carry or directthe sheets against or into contact with the glueroll, is, however, of great importance and involves an important improvement in machines of this character, for the reason that by the use of such guide I vam enabled to secure the contact of the entire surface of the strip or sheet with the glued surface of theglue-roll withoutthe necessity of using any presser-roll to hold or press the sheet against the glue-roll, and thereby avoid liability of transferring the glue or paste to the unglued side of the strip or sheet. A second guide, as the guide-bar to, while desirable to insure the advance of the front edges of the strips to the glue-roll, is not essential, inasmuch as the guide-bar u or other similarly-placed guide, so located that the paper is drawn against it in the turning of the glue-roll, will alone serve the purpose of directing the paper into contact with the roll. As, for instance, if the glue-roll were rotated in a direction the reverse of that shown in the draw ings, so as to feed the paper against the downwardly-moving side of the roll, then the paper would be drawn against the lower guidebar, and inasmuch as it would rest upon said bar by gravity at all times any additional or opposite guide would in that case be unnecessary.

A further important improvement is involved in the construction by which the glueroll is made to revolve slightly faster than the roll which forms part of the feeding devices, so that the strips or sheets are strained or drawn closely against the glue-roll, and this, as well as other features of construction herein shown and described, are herein claimed as part of my invention.

I claim as my invention- 1. In a machine for applying adhesive substances to paper and similar material, the combination, with a glue-roll, of a paper-feeding device for carrying the sheets of paper toward the glue-roll, a guide between the paper-feeding device and the glue-roll, acting to direct the paper against or into contact with the glue-roll, and take-off fingers for separating the paper from the g1ue-roll, substantially as described. 7
